How do you eliminate them? The vast majority of types in debug info
are duplicate header file types coming from different source files.
Reducing this should cut the number much more drastically than
from 120k to 80k. I'd say by factor of 8 at the very least. 

My code which reads stabs info says that there are 52276 types (not
trying to remove duplicates) defined
in gdb (not including libbfd, libiberty and libopcodes; including them
gives another 13000 or so) and of them 886 unique type *names*. This
gives a lower bound, obviously, since names may be reused or may denote
different types even coming from the same header due to different defines --
but it's also more useful than the raw number since it doesn't count the
multitude of unnamed automatically generated types which are pointers, 
aliases, forward references, etc.

That would mean around one type name per 400 lines of code. Since almost all
type declarations are in header files which are about 1/10 of all sources
in size, it looks reasonable.
